Eukaryotic mRNA decay: methodologies, pathways, and links to other stages of gene expression

TLDR
Recent genome-wide methods for determining mRNA half-lives in eukaryotes are discussed and pre- and posttranscriptional regulons that coordinate the fate of functionally related mRNAs by using protein- or RNA-based trans factors are reviewed.

Cytoplasmic 5 -3 exonuclease Xrn1p is also a genome-wide transcription factor in yeast

TL;DR: This work shows that disruption of Xrn1 activity preferentially affects both the synthesis and decay of a distinct subpopulation of mRNAs, and proposes to name the most affected genes “Xrn1 synthegradon.”

Ribosome Profiling Reveals Pervasive Translation Outside of Annotated Protein-Coding Genes

TL;DR: Hallmarks of translation in ribosome footprints are shown: copurification with the large ribosomal subunit, response to drugs targeting elongation, trinucleotide periodicity, and initiation at early AUGs.
Journal ArticleDOI

Gene Expression Is Circular: Factors for mRNA Degradation Also Foster mRNA Synthesis

TL;DR: It is demonstrated that most yeast mRNAs are degraded by the cytoplasmic 5'-to-3' pathway (the "decaysome"), as proposed previously, and the level of these m RNAs is highly robust to perturbations in this major pathway because defects in various decaysome components lead to transcription downregulation.
Journal ArticleDOI

mRNA transcript therapy

TL;DR: The current state of mRNA drug technologies and potential applications are presented, as well as discussing the challenges and prospects in mRNA development and drug discovery.

Exosome-mediated transfer of mRNAs and microRNAs is a novel mechanism of genetic exchange between cells

TL;DR: It is shown that exosomes contain both mRNA and microRNA, which can be delivered to another cell, and can be functional in this new location, and it is proposed that this RNA is called “exosomal shuttle RNA” (esRNA).

Global quantification of mammalian gene expression control

TL;DR: Using a quantitative model, the first genome-scale prediction of synthesis rates of mRNAs and proteins is obtained and it is found that the cellular abundance of proteins is predominantly controlled at the level of translation.

Identification and analysis of functional elements in 1% of the human genome by the ENCODE pilot project

Ewan Birney, +320 more
- 14 Jun 2007 - 
TL;DR: Functional data from multiple, diverse experiments performed on a targeted 1% of the human genome as part of the pilot phase of the ENCODE Project are reported, providing convincing evidence that the genome is pervasively transcribed, such that the majority of its bases can be found in primary transcripts.

Genomic expression programs in the response of yeast cells to environmental changes.

TL;DR: Analysis of genomic expression patterns in the yeast Saccharomyces cerevisiae implicated the transcription factors Yap1p, as well as Msn2p and Msn4p, in mediating specific features of the transcriptional response, while the identification of novel sequence elements provided clues to novel regulators.

Chromatin signature reveals over a thousand highly conserved large non-coding RNAs in mammals

TL;DR: It is demonstrated that specific lincRNAs are transcriptionally regulated by key transcription factors in these processes such as p53, NFκB, Sox2, Oct4 (also known as Pou5f1) and Nanog, defining a unique collection of functional linc RNAs that are highly conserved and implicated in diverse biological processes.
